This will not affect the performance of the rest of the set. 4) Due to

13、 the short flex cable wires in the ETF Module, the pc board should be disconnected and reconnected on the reverse side of the tape mechanism to keep it electrically connected during repair. See picture 3. Note: The flex cables are very fragile, care should be taken not to damage them during repair.

14、After repair, be very sure that the flex cables are inserted properly into the flex sockets before encasing, otherwise faults may occurs.

This can happen when either the switch is defective and closed all the time, or when the carousel is blocked when located exactly at a disc position. The carousel position switch did not close within a certain time. This can happen when the swi
